+Description
+===========
+    This example demonstrates basic usage of the IDirectDraw7::StartRefreshRate
+    and IDirectDraw7::EvaluateMode methods. Together, these methods allow an
+    application to explore what display modes and refresh rates the monitor
+    connected to this display device is able to display, though a manual
+    user-controlled process. The application will present the UI that asks
+    the user if the current mode under test is being displayed correctly by
+    the monitor.
+
+    Applications should use these methods when they are interested in using
+    higher refresh rates.
+
+    The basic idea is that DirectDraw will setup a list of modes to be tested
+    (based on the list the app passed in), and then sequentially test them
+    under application control. The app starts the test process, and then
+    calls IDirectDraw7::EvaluateMode continuously. DirectDraw will take care
+    of settings the modes. All the app has to do is SetCooperativeLevel
+    beforehand, and then handle surface loss and drawing the UI that asks the
+    user if they can see the current mode under test. DirectDraw returns
+    enough information from IDirectDraw7::EvalulateMode to allow the app to
+    know when to do these things, and when to stop testing. The app can pass
+    a flag to IDirectDraw7::EvaluateMode if the user happened to say they
+    could see the mode corretly, which will cause DirectDraw to mark the mode
+    as good and move on. DirectDraw may also decide that time as run out and
+    give up on a certain mode.
+
+    DirectDraw uses information at its disposal from any automated means to
+    make the testing process as short as possible, and applications only need
+    to test modes they are interested in.

+User's Guide
+============
+  The user interface is a simple dialog box. First select the DirectDraw display
+  device.  Then select which modes you would like to test, and click 'Test'.   
+  Each display mode will be tested, and the user can select if the mode appears
+  correctly or not. 
+  
+  If the user makes a mistake, and accidently says YES when a mode cannot be seen, 
+  or NO when a mode really can be seen (thus ending up with a lower refresh rate than 
+  possible) this allows the user to reset the test results and try again.  
+  
+  Click the Exit button to exit the application.
